High Dynamic Range 3D Display System with Projector and 3D Color Printer Output

This demonstration describes a new high dynamic range (HDR) display system that generates a physical 3D HDR image without using stereoscopic methods. To boost contrast beyond that obtained using either a hardcopy or a projector, we employ a multiprojection system to superimpose images onto a textured solid hardcopy that is output by a 3D printer or a rapid prototyping machine. The physical contrast ratio obtained using our method was approximately 5,000:1, while it was 5:1 in the case of viewing the 3D printout under environmental light and 1,000:1 in the case of using the projectors to project the image on regular screens.
